How Do You Use A Polybius Square?
• Design a Polybius square (see image). • A Polybius Square Create an equal number of numbered rows and columns (see image). To determine how many rows and columns to make, find the square number (also called a perfect square) that is nearest to the number of letters in your alphabet. Then take the square root of that square number–this will be the number of rows and columns in your Polybius square. For example, in the English alphabet, there are 26 Write Different letters. The closest square number to 26 is 25, and the square root of 25 is 5, so you would need 5 columns and 5 rows, as shown in the image. Other languages use alphabets with more or fewer letters, so depending on the language used, the Polybius square may have more or fewer than 5 rows and columns. • Write the letters of the alphabet in your grid. There should be one letter at the intersection of each row and column. In the simplest form, you can just write the alphabet out in order, but if you want to make the code har
